Units going into auto protect are usally due to open or dead short conditions to keep the system protected from blowing the final amps. based on what you suggested I woould test or change out the cables 1st.

SOURCE: Kef Q Series iQ1 problem

You may have broken the cross over, which is fixable by an service agent, or you may have damaged the voice coil in the mid driver. you can check this by sofly pushing the main driver in, making sure that you done push the cone, if there is a lot of resistance then you have damaged the voice coil, and you will need to replace the driver.

These are quite common, and are just separate connection for each speaker in the enclosure. Just bridge the connections red to red and black to black with cable (use something like 5amp house wiring cable) and then connect your cable from your amplifier to one of the "ports" See http://www.brilliancehifi.co.uk/how-to-bi-wire-speakers.htm As you can see you could "biwire" if you wanted go further and improve the sound quality

SOURCE: I need the wiring diagram

There are just 4 wires connecting in that jack: 2 grounds and 2 hot. You can identify them yourself directly either just by looking at the rear pins (where and how they are soldered on the board) after you remove the back cover, or by testing them with an ohmmeter (to the metal side of the jack): the 2 ground wires will show 0, the empty ones will show infinite and the hot ones will show 0 in the moment when you connect it then the resistance will grow fast toward infinite (if after that you reverse the polarity of the test wires you will get initially a negative resistance).

My Dad had the same problem. KEF admitted it was a paint problem and replaced the speakers.

What are the color connector labels


Red is positive, black is negative. Your receiver, or amp, will have similar color coded terminals. Just make sure you run a wire from the red terminal on your receiver to the red terminal on your speaker. Same thing for the black.

Hi i have a kenwood A-97 keeps saying protect on the amp can you help


Hi,

The amp will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. verify that none of the speaker wire connections are loose at the back of the receiver or at each speaker. And verify that none of the wires are making contact with each other.

if it is, then remove the speaker wires and connect them again properly. After disconnection g the speaker wires, unplug the receiver for 10 to 15 minutes. This will make the overload protection back to normal

Try this and let me know. I hope this would solve the issue

Regards.

Please send me a diagram of how the wiring is to be set up on the back of the speakers


The red connector on the speaker should be connected to the Pos.(+) connection on the Receiver/Amp. The Black to the Neg. (-) connection. ( for the proper speaker) Front Left, Front Right,etc. All, or most paired wire has either a black stripe,different shape on one,or different colour wire(silver/copper) So if you hook up the Blk striped or silver to the Neg.(black terminal) on the speaker, do so at the other end (receiver ) If both speakers aren't hooked up the same, they will work, but there won't be as much Bass because the speakers will be out of phase.(when one speaker cone is moving out,the other will be moving inward.

Morning I have a set of KEF Q 5 floor standing


I'd suspect a shorting voice coil in the woofer or a loose connection inside that vibrates and presents a wildly varying load.

Disconnect the bi-wiring jumpers and try driving each 'half' separately as a test for tripping the amp.

Can KEF Cresta be connected as Bi-AMp configuration ?


If you have posts that look like this, yes - just make sure the straps (connecting the red to red, etc) are removed.

Im having trouble with connections from kef psw 1000 sub to onkyo tx sr506 amp. sub is making a bit of a humming noise but not getting any proper sound through. dont know what im doing wrong. can anyone...


Have you got the sub defined to the Onkyo correctly? Try conencting the sub's input to one of the Tape Out connectors and play some FM through it. That will prove if the sub is alive. The nwe can troubleshoot the correct failing device.

I have a Kef PSW 2500 that emits a loud buzz when on. I pulled the amp, but I'm not sure if its the speaker or amp. What should I be looking for the speaker outputs from the AMP? How can I tell if its a...


Have just repaired a similar problem with a KEF 2500 - relay was chattering at 50 Hz rate, buzz in speaker output.

Problem was caused by overheated / dried out Electrolytic filter cap (C52 - 47uF 63V) on the relay coil supply feed.
The overheating is caused by adjacent power supply dropping resistors which run very hot due poor design of power supply.

A service manual for a similar model is available at following link, refer to power supply section:-
http://www.eserviceinfo.com/downloadsm/35375/kef_psw2000.html

To replace,
1) remove chassis from speaker cabinet (8 screws), disconnect red/black speaker wires from main PCB spade connectors.
2) Remove 4 screws attaching main pcb heatsink assembly from face panel - lift assembly from faceplate (a bit messy , much heartsink compound between mounting faces)
3) unplug the AC 3 pin connections adjacent to the large capacitors and the 3pin connector on end of pcb (near C52), then roll assembly over the top of the audio sub-board to access underside of pcb.
4) solder connections to C52 is accessible at edge of board without further dis-assembly.
Take extreme care replacing C52, as the circuit board is of poor quality, (usual domestic electronics quality) being single sided copper without plated through holes.
The board is already heat damaged by heat buildup from power supply resistors, so the track will most likely lift and crack when disturbed- to counter this problem link the +ve capacitor pigtail to an adjacent solder pad on the same track.
Assembly is reverse of above, take care to preserve/ensure minimum disturbance of heatsink compound.

I have 2 KEF Q35 speakers, i have them wired up as normal on the outside ports, but there are another set of wiring ports labelled HF (one positive one negative) what are these for? please help!!

Cant connect my q35 speaker, help please!! Theres 4 connections??


Hi, They should have a gold bar "jumper"between the two black/and the two red connectors. If not, it is missing,but the reason for that is you can use seperate amps for the woofer and the tweeter/mid.Called "Bi-amping."You can just use a extra wire to connect both inputs together. Black to black and red to red.
